SPECIFICATION forming part of Letters Patent No. 651,519, dated June 12,1900. Application filed September 22, 1899. Serial No. 731,504. (Nomodel.)

To a whom it near; concern:

Be it known that I, FRANcoIs ALeoUD,chief engineer of State railway, acitizen of the Re public of France, residing at La Valliere,Indre-et-Loire, in the Republic of France, have invented certain new anduseful Improvements in Apparatus for Testing and Regulating the Positionof the Rails in Railway- Tracks, (for which I have made application forpatent in France on February 23, 1899,

and in GreatBritain on August 30, 1899;) and- I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This apparatus for testing and regulating in other words,maintaining-railway-tracks consists in part of apparatus for testing oradjusting the necessary distance between the railsfor example, first,after ballasting the permanent Way; second, in straightening the track,and, third, upon the necessary widening of the distance between therails at curves of small radius in order to facilitate the traveling oflocomotives and carriages. The apparatus comprises, further, anarrangement which enables the superelevation of the outer rail at acurve to be tested and adjusted, and, further, for the testing of therail inclination a suitably-arranged edge is provided in sucharrangement.

The accompanying drawings illustrate this apparatus, which is intendedto supersede the three contrivances hitherto used in railwaymaintenanceviz., the iron templet for the gage of way, the templet forthe superelevation of the outer rail at curves in the track, and,thirdly, the water-level which must be used for the superelevation ofthe outer rail, together with the templet.

Figure 1 is a side view of the one end of the apparatus; Fig. 2, asimilar view of the other end, and Figs. 3 and 4 are end views.

The end shown in Fig. 1 comprises a steel plate which is straight on'the upper side, the under end being furnished with a shoulder having twointerruptions or deviations which correspond to two similar forms in theother end of the apparatus. (Illustrated in Fig. 2.) This steel plate isfixed by means of screws to the left-hand end of a rectangular woodenrule-board. On the steel plate an angle-iron is arranged to turn, whichforms an additional deviation for the first deviation of Fig. 2 and canbe turned into and out of the working position, as desired. In order toturn this angle-iron into the working position, it is sufficient to moveit to the left until the one arm rests on the stop shown in Fig. 1. Theposition of the angle-iron (indicated by dots, Fig. 1) shows the workingposition,while the position represented in unbroken lines is that ofrest. These two parts of Fig. 1 each have abronze tablet, on which thecorresponding gage of way is indicated by figures.

Fig. 2 likewise shows a steel plate and, in fact, that of the other endof the apparatus, which is furnished at the lower end with a shoulderhaving two interruptions or deviations corresponding with those inFig. 1. This part, Fig. 2, is fixed t0 the other end of the woodenrule-board. The upper part of the plate, Fig. 2, is of trapezium formwith rounded-oft edges, and carries a pendulum which rests on aknife-edge and in its position of rest indicates the vertical inwhatever position on the two rails the apparatus maybe. A stapleprevents excessive swinging of the pendulum, while a widening at thelower end of the latter serves to keep it in the right direction. Thelower end of the pendulum terminates in a point and moves over a scale.

This scale is so arranged that its zero-point lies in the middle of itsgraduations. If the pendulum is over the zero-point, the surfaces of theapparatus lying on the upper edges of the rails form a horizontal. Thevariations of the point of the pendulum from the one or other side ofthe zero-point indicate the deviations of the upper edges of the railsto the one side or the other.

This apparatus enables the track to be promptly tested and thesuperelevation of the one rail-head at curves in the track to bedetermined without the necessity of employing a water-level.

The upper part of Fig. 2 has a wedge somewhat deviating from theperpendicular for testing the inclination of the rails.

The arrangement can be employed for all kinds of railway-tracks.

What I claim, and desire to secure by Letters Patent, is

1. Apparatus for regulating and testing the position of the rails inrailway-tracks, distinguished by a wooden rule-board, the one end ofwhich bears on a steel plate with a shoulder which has two interruptionsor deviations and a turning angle-iron for the formation of a furtherdeviation while the other end like wise has a steel plate furnished withsimilar deviations and having on its upper side a raised extension onwhich a pendulum hangs, which indicates on a scale the position of theapparatus, laid on the upper edges of the rails in relation to thehorizontal.

2. Apparatus for regulating and testing the position of the rails inrailway-tracks, distinguished by a wooden rule-board, the one end ofwhich bears on a steel plate with a shoulder which has two interruptionsor deviations and a turning angle-iron for the formation of a furtherdeviation while the other end likewise has a steel plate furnished withsimilar deviations and having on its upper side a raised extension onwhich a pendulum hangs, which indicates on a scale the position of theapparatus,laid on the upper edges of the rails, in relation to thehorizontal, while an oblique edge of the extension serves for testingthe inclination of the rail.

In testimony whereof I aflix my signature in presence of two witnesses.

FRANCOIS ALGOUD.
